Definitions

  • the present invention relates to a device for filtering a fluid contaminated with particles. More specifically, but without restriction to the particular embodiment and/or use which is shown and described for purposes of illustration, the present invention relates to a device for filtering a fluid contaminated with particles used on an exhaust gas transporting particulate matter from an engine.
  • Filter devices of porous materials are generally known, these filter devices usually being arranged in an outside container.
  • Serving here as the material for the filter devices is generally a porous material which may be, for example, a sintered material composed of metallic materials or else of glass or plastics.
  • the filter devices are usually made up of filter plates of the porous material mentioned above lying one behind the other in an outer container.
  • the filter devices When the filter devices are used as a particulate filter for the exhaust gases of an engine, the filter device and silencer in the exhaust line of the engine are often combined to form one unit.
  • the fluid to be filtered must penetrate one or more layers of the porous material to achieve an adequate cleaning effect. Due to the large surface areas of porous material required, this results in multi-layered filters which oppose the flowing fluid with a very high flow resistance.
  • U.S. Pat. No. 2,926,743 discloses a free-flow silencer for an exhaust system which comprises two tube elements lying one inside the other, the inner one of the tube elements having a cross-sectionally star-shaped form, which opens out into the outer tube with a terminating element in the manner of a Venturi nozzle.
  • This free-flow silencer is capable of cooling the exhaust gases, reducing their flow velocity and effectively avoiding their pressure fluctuations. As a result, very efficient cooling and silencing of the exhaust gases in the exhaust system is achieved.
  • the actual filter unit in the outer container is formed according to the invention by a porous material that extends in the direction of flow being repeatedly folded along this direction of flow and joined together by the free ends, so as to produce a cross-sectionally closed geometrical form which has at least one inner opening.
  • the material may thus be folded, for example, in the manner of a multi-pointed star, so that a kind of tube with a star-shaped cross section is produced from the porous material.
  • the fluid to be filtered then penetrates this star-like structure from inside to outside or from outside to inside, by the fluid either being introduced into the porous material and flowing from there into the region of the outer container or by the fluid being allowed into the outer container and then drawn out of the least one internal opening in the cross section of the porous material.
  • the folds make it possible, according to their number, to accommodate a quantity of surface area that is adapted in the best way possible to requirements, or is as great as possible, in the outer container, the geometrical dimensions of which are usually prescribed.
  • the outer container with the filter device serves not only for filtering an exhaust gas contaminated with particles but at the same time as a silencer. This means that any pressure waves there may be in the exhaust gases are reduced by the unit comprising the outer container and filter device, so that no disturbing noises can be emitted to the area surrounding the system.
  • the great porous surface area is also almost ideal for this, since it makes possible corresponding acoustic effects which allow the sound waves in the exhaust gas to “run their course”.
  • FIG. 1 shows a basic representation of a cross section through the device according to the invention
  • FIG. 2 shows a longitudinal section through the device according to the invention along line II—II in FIG. 1;
  • FIG. 3 shows a basic representation of a cross section through a further embodiment of the device according to the invention.
  • FIG. 4 shows a longitudinal section along the line IV—IV in FIG. 3;
  • FIG. 5 shows a basic representation of a cross section through a further possible embodiment of the device according to the invention, with a combination of several filter devices;
  • FIG. 6 shows a further alternative embodiment of the device according to the invention, with a combination of several filter devices.
  • a device for filtering a fluid contaminated with particles is provided.
  • numerous specific details are set forth in order to provide a more comprehensive description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, specific details of well-known features have not been described so as not to obscure the present invention.
  • FIG. 1 shows a cross section through an embodiment of a device 1 for filtering a fluid laden with particles, or a particle filter 1 .
  • the filter device 2 is arranged in an outer container 3 .
  • the filter device 2 includes a plurality of folds extending in the direction of the gas flow.
  • the cross section of the filter device has a closed geometric form that includes an inner opening 4 .
  • An inner tube 5 is provided to act as a supporting structure.
  • the inner tube or supporting structure 5 serves for stabilizing the filter device 2 , which consists of a porous material 6 or sintered material 6 and is divided by numerous folds into a multiplicity of tine-like subregions 7 .
  • the inner tube 5 is formed in the region extending in the interior of the filter device 2 from a perforated material or grid-like material (cannot be seen in the representation) or at least has openings which join the inner opening 4 to the inner spaces 8 of the tine-like subregions 7 .
  • FIG. 2 Represented in FIG. 2 is a cross section along the line II—II in FIG. 1 .
  • the outer container 3 in this case encloses the filter device 3 with its tine-like subregions 7 .
  • Fitted onto the end region represented of the outer container 3 is a metal terminating plate 9 , which seals off the outer container and through which an end region 5 a of the inner tube 5 extends.
  • this end region 5 a of the inner tube 5 has no radial openings in the region within the filter device 2 .
  • a collecting plate 10 which provides a gastight transfer of the flowing fluid between the filter device and the end region of the inner tube 5 .
  • FIG. 3 Represented in FIG. 3 is an alternative embodiment of the particle filter 1 . It operates on the same functional principle and also has a comparable construction to the embodiment represented in FIG. 1 . The only difference in comparison with FIG. 1 is that here the form of the outer container 3 does not have a round but an oval geometrical shape. The same applies in a comparable way to the inner tube 5 in the exemplary embodiment represented. However, it would also be quite conceivable to use a circular inner tube 5 , even if the outer container 3 has an oval cross section.
  • the tine-like subregions 7 are arranged here by means of the folds in such a way that they each have a different radial extent from the inner tube 5 to the outer container 3 . Consequently, the porous material 6 can be adapted by a simple alteration of the spacings between the individual folds in such a way that the filter device 2 is able to utilize as ideally as possible the space available between the inner tube 5 and the outer container 3 .
  • FIG. 4 Represented in FIG. 4 is a further possible way of joining the filter device 2 to the end region 5 a of the inner tube 5 .
  • the porous material 6 of the filter device 2 is compressed around the end region 5 a of the inner tube 5 and joined to the end region 5 a of the inner tube 5 by adhesive bonding, soldering or welding.
  • FIGS. 2 and 4 can be used in every conceivable form and arrangement of the tine-like subregions 7 and of the outer container 3 .
  • An alternative possibility which is not represented in the exemplary embodiments, may also dispense with the use of an inner tube, the compressed ends of the filter device 2 then also being able to be pressed from inside into a connecting piece of pipe, comparable with the, end region 5 a of the inner tube 5 , and welded or soldered or adhesively bonded.
  • the functional principle of the filter device 2 is approximately the same here in both directions of flow, so that the fluid contaminated with particles can on the one hand be introduced into the outer container 3 and discharged from the inner opening 4 of the filter device 2 or on the other hand can be introduced via the inner opening 4 and drawn out via the outer container 3 .
  • nothing about the way in which the particle filter 1 functions or is constructed changes as a result of the one or other direction of flow.
  • a connection between one end of the tube according to the embodiment explained in FIG. 4 may be provided on one side, for example, while at the other end the fluid is introduced or drawn out via a collecting plate 10 in such a way that the connecting pipe there is in connection with the space between the outer container 3 and the filter device 2 .
  • FIG. 5 shows a further embodiment of the particle filters 1 , eight filter devices 2 having been combined here to form a unit.
  • the exemplary embodiment represented in FIG. 5 has dispensed with the use of inner tubes 5 . This is possible if the sintered material 6 has an adequate wall thickness and strength to allow the filter device 2 to be designed as a self-supporting part.
  • the square embodiment of the respective filter device 2 shows that the inner opening 4 may also be of any desired form, here likewise a square form.
  • FIG. 6 shows a further exemplary embodiment with a combination of three filter devices 2 , which fill the greatest part of a respectively rectangular space, and are combined to form an overall unit.
  • each of the filter devices 2 does not have to have its own outer container 3 , but that a number of filter devices can be combined in a single outer container 3 .
